Unified Aerosol Microphysics for NWP 30 Sep 2011 6 pages
Authors:  Douglas L Westphal; Stephen A Lowder; James D Doyle; Jeffrey S Reid; Jermone Schmidt; NAVAL RESEARCH LAB MONTEREY CA
The full text of this report is available for sale.The long-term goal of this research is to develop a practical predictive capability for visibility and weather effects of aerosol particles over any region of the world for timely use in planning and executing DOD operations and activities. Specifically, the goal is to develop a COAMPS that is capable of simulating the full range of interactions between aerosol particles, clouds, and radiative transfer while remaining flexible, extensible and operationally practical. ...


Large-Scale Aerosol Modeling and Analysis 30 Sep 2010 7 pages
Authors:  Douglas L Westphal; Cynthia A Curtis; Annette L Walker; NAVAL RESEARCH LAB MONTEREY CA
The full text of this report is available for sale.The long-term goal of this research is to develop a practical predictive capability for visibility and weather effects of aerosol particles for the entire globe for timely use in planning and executing DoD operations and activities. The fundamental predicted variables are the concentrations of atmospheric aerosol particles responsible for degradation of Electro-Optical (EO) propagation in regions of DoD interest. Post-processors calculate the optical parameters useful in strategic and tactical planning, ...

A System for Operational Aerosol Optical Depth Data Assimilation Over Global Oceans Jan-2008 14 pages
Authors:  Jianglong Zhang; Jeffrey S Reid; Douglas L Westphal; Nancy L Baker; Edward J Hyer; NAVAL RESEARCH LAB MONTEREY CA MARINE METEOROLOGY DIV
The full text of this report is available for sale.In this study, we present an aerosol data assimilation system destined for operational use at the Fleet Numerical Meteorological and Oceanographic Center (FNMOC). The system is an aerosol physics version of the Naval Research Laboratory (NRL) Atmospheric Variational Data Assimilation System (NAVDAS) that is already operational. The purpose of this new system, NAVDAS-Aerosol Optical Depth (NAVDAS-AOD) is to improve the NRL Aerosol Analysis and Prediction System (NAAPS)'s forecasting capability by ...
